2. Show your calculations for producing 10 mls of the following standards (in ppb) using the 500 ppm Pb2+ stock solution: 200, 100, 50, 10, 5, and 1 ppb. Be sure to carry out a serial dilution from the 500 ppm stock solution to achieve these concentrations. Dilutions should be no greater than ten-fold. Assume 10, 20, 25, 50, 100mLvolumetric flasks, 1,2,3,4,5,6,7,8,9,10,15,20,25 mL volumetric pipets and 50mLburettes are available for use. (10 pts)
